The policy infrastructure of U.S. intelligence community is defined by directives issued by the Director of National Intelligence on everything from security policy to roles and missions to relations with Congress.
The new system of policy statements, known as Intelligence Community Directives (ICDs), is the successor to the former Director of Central Intelligence Directives (DCIDs). The new ICDs are gradually supplementing, modifying or replacing the existing DCIDs.
The DNI has also issued a series of Intelligence Community Policy Memorandums (ICPMs), which are initial statements of policy that have not yet been formalized as an ICD.
They cover such topics as open source intelligence, personnel security, the role of the IC analytic ombudsman, the roles of the various Deputy Directors of National Intelligence, and the use of portable electronic devices in secure facilities.
